SPECIFICATION forming part of Letters PatentNo. 609,504, dated August 23, 1898. Application filed January 24, 1898. Serial No. 667,789- (No model.)

To all whom it may concern:

Be it known that I, ALGAE T. 'FENNER, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Supporting Attachments for Bicycles, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

My invention relates in general to attachments for bicycles of that class designed to be secured to the frame of the bicycle for the purpose of supporting the latter in an upright or normal position when at rest, whether mounted by the rider'or unmounted.

In the accompanying drawings, Figure 1 is a side elevation of parts of an ordinary bicycle, showing my invention attached in place. Fig. 2 is a cross-section of a part of the frame and the supporting device, taken on the broken dotted line 2 2 in Fig. 1. Fig. 3 is a front elevation of the supporting device and some associated parts, seen as indicated by arrow 3 in Fig. 1. Fig. 4 is a cross-section of a part of the frame and main rod of the supporting device, taken on the dotted line 4 4111 Fig. l. V Fig. 5 is a plan of the upper hanger with parts broken away and other parts horizontally sectioned on the broken dotted line 5 5 in Fig. 6. Fig. 6 is aside elevation of the upper hanger, seen as indicated by arrow 6 in Fig. 4, parts being broken away and other parts vertically sectioned on the broken dotted line 6 6. Fig, '7 is a front elevation of the lower part of the supporting device detached. Fig. 8 shows more clearly the method of locking the supporting device, parts being in vertical section. Fig. 9 is a cross-section of the main rod of the supporting device above the tripod on the dotted line 9 in Fig. 7. Figs. 2, 4, 5, 6, and 9 are drawn full size.

Figs. 1, 3, and 7 are drawn to a scale of one fourth full size, and Fig. 8 to an exaggerated scale to better show the construction.

In the drawings, A is the rear wheel of a bicycle, l3 and 0 being portions of the frame. D is my new attachment for holding the bicycle steady and upright. This attachment comprises a main rod or and a tripod 50 consisting of legs'b, b, and c to rest at their lower ends upon the ground and means for securing the device to the frame and for operating it. The rod a is held near its upper end bya hanger E, clamped onto the frame, and near its lower end by another hanger F, also secured to the frame, the two hangers being adjustable on the part 0 of the frame. Thus held the device occupies a position just forward of the rear wheel of the bicycle and between said wheel and the frame, passing through the fork H.. Thelower hanger F is provided with an expanded foot G, (see Fig. 2,) through perforations in which the four rods a, b, b, and 0 pass, all said rods being adapted to be moved substantially vertically in the hangers E and F. The openings in the foot-piece G occupied by the legs 19, b, and c are equidistant from each other or made at the angles of an equilateral triangle.

The main rod (1 terminates at the bottom in a threaded end provided with a screw-nut cl, at some distance above which and above the foot-piece G is secured rigidly a yoke or holder 6, Figs. 3, 7, and 9, in which are pivotally hung independently of each other the three legs b b c of the tripod. Now it will be understood by viewing Fig. 1 that if the rod a be pulled upward the legs of the tripod will bedrawn through the part G and will be brought near together at their lower ends or bunched and caused to occupy the closed position shown in Fig. 3 and in dotted lines in Fig. 1. This is the position of the device when not in use, it being in a compact form and out of the way. It will be also understood that if when the legs are bunched the rod (1 be pushed downward the legs will be spread to form a broad base to rest upon the ground, as appears in full lines in Fig. 1, the foot-piece G thus serving to bunch or to spread the legs of the tripod as they are moved throughit.

The rod a is provided at its upper end with a thumb-piece f in convenient reach of the rider, by means of which to manipulate the device while mounted, if necessary or convenient. When the parts are drawn upward,

the nut d, encountering the hanger F, constitutes a stop for the upward motion of the parts.

The device is held in its upper position against the action of gravity by means of spring-actuated locking-levers or catches g g acting against the rod ct. These levers are placed one vertically over the other, both being pierced by the rod a, each having a sort of pivotal motion in an inclosed part it of the hanger E. The actuating-spring '1; is coiled upon the rod a between the levers and serves to keep the latter wide apart. Viewing Fig. 8, it will be understood how the levers act to hold the rod a stationary. The openings 70 7c in the levers for receiving the rod are larger than the latter in diameter, so that when the levers are pressed by the thumb and finger of the rider toward each other into substantially parallel positions the rod may freely move through them; but when left to the action of the spring the inclined positions of the levers cause them to bind the rod and prevent it from moving downward on account of gravity.

What I claim as my invention is 1. The combination with the upper hanger, of the lower hanger having depending portion and laterally-expanded foot, the main rod movable through openings in said hangers,the three-armed yoke secured to said rod above the said foot, the rods pivotally connected to the arms of said yoke and passed through openings in the foot at the angles of an equilateral triangle, and means for holding the rods in their uppermost position,substantially as shown and described.

2. The combination with the upper hanger, and the lower hanger having a depending portion terminating in laterally-extending expanded foot, of the main rod movable throughopenings in said upper hanger and said foot, the three-armed yoke secured to the rod above the foot, the rods pivotally connected to the arms of said yoke and passed through openings in the foot, means for holding the rods in their uppermost position, and a nut on the 40 lower end of the main rod to engage said foot y to limit the upward movement of the rod, all

substantially as and for the purpose specified. In witness whereof I have hereunto set my hand, this 20th day of January, 1898, in the 45 presence of two subscribing witnesses.
